NXP Semiconductors S9S08LG32J0CLK

Overview

S9S08LG32J0CLK from NXP Semiconductors (formerly Freescale) is an 8-bit HCS08 microcontroller with 32 KB flash, 1984-byte RAM, and integrated LCD driver supporting up to 8×37 segments. It operates from 2.7 V to 5.5 V across –40 °C to 105 °C, features dual TPM modules (6+2 channels), 12-bit ADC with 16 inputs and temperature sensor, and supports LIN-compliant SCI for automotive body control applications.

For engineers reviewing the S9S08LG32J0CLK datasheet, S9S08LG32J0CLK pinout, S9S08LG32J0CLK application, or S9S08LG32J0CLK equivalent, key selection criteria include its low-power stop3 mode (100 µs wakeup), on-chip ICS with ±2% FLL accuracy over voltage/temperature, 80-pin LQFP package with 69 GPIOs, and integrated real-time counter with external clock support.

Technical Context

The S9S08LG32J0CLK implements the HCS08 CPU core with BGND instruction support and handles up to 32 interrupt/reset sources. Its internal clock source (ICS) uses a frequency-locked loop (FLL) trimmed to 0.2% resolution, enabling bus frequencies from 1 MHz to 20 MHz with ±2% deviation across full operating range.

Peripherals include two timer/PWM modules (TPM1: 2-channel, TPM2: 6-channel), a 12-bit ADC with 2.5 µs conversion time and wake-from-stop3 capability, and dual SCI interfaces with LIN master/slave extended break generation/detection - all functional within the same 80-pin LQFP footprint and voltage range.

FAQ

What is the maximum bus frequency supported by the S9S08LG32J0CLK?

The S9S08LG32J0CLK supports a maximum bus frequency of 20 MHz, achieved via its internal clock source (ICS) module with frequency-locked loop (FLL). This is attainable across the full operating voltage range (2.7 V to 5.5 V) and temperature range (–40 °C to 105 °C), with ±2% deviation guaranteed. The S9S08LG32J0CLK achieves this using precision trimming of the internal reference oscillator, enabling stable timing without external crystals in many applications.

Does the S9S08LG32J0CLK support wake-up from stop3 mode using the ADC?

Yes, the S9S08LG32J0CLK supports wake-up from stop3 mode using the ADC. Its 12-bit ADC remains fully operational during stop3, including automatic compare function and temperature sensor channel. A conversion completion or compare match event can trigger exit from stop3 with typical wakeup time of 100 µs. This capability is explicitly confirmed in the "Peripherals" section of the MC9S08LG32 Rev. 9 datasheet and enables ultra-low-power sensor polling in battery-operated devices like medical handhelds.

What package type and pin count does the S9S08LG32J0CLK use?

The S9S08LG32J0CLK uses an 80-pin LQFP package (Case 917A, 14 mm × 14 mm). This is confirmed in the "Package Options" section of the MC9S08LG32 Rev. 9 datasheet and Figure 2 (80-Pin LQFP). It provides 69 GPIOs and full peripheral access, including all LCD segments (up to 8×37), dual SCI, SPI, IIC, TPM, and ADC channels - distinguishing it from the 64-pin and 48-pin variants of the same family.

Can the S9S08LG32J0CLK drive an 8×37 LCD without external components?

Yes, the S9S08LG32J0CLK can drive an 8×37 LCD without external bias components. It integrates a charge-pump-based LCD driver with internal voltage boosting, supporting up to 8×37 or 4×41 segments. The driver includes programmable contrast control and operates directly from the main VDD supply. This capability is documented in the "Peripherals" section and Figure 1 block diagram of the MC9S08LG32 Rev. 9 datasheet, eliminating need for external LCD bias ICs in cost-sensitive HMI designs.

Is the S9S08LG32J0CLK qualified for automotive applications?

Yes, the S9S08LG32J0CLK is qualified for automotive applications. It is rated for operation from –40 °C to +105 °C, meets AEC-Q100 stress test qualification for ESD (HBM ≥2500 V) and latch-up immunity, and includes automotive-specific features such as LIN-compliant SCI with extended break generation/detection and COP watchdog with dedicated 1 kHz clock option. These qualifications and features are detailed in the MC9S08LG32 Rev. 9 datasheet Sections 1–4 and Table 21.
